This is the first I've heard about that. I wish the same could be said for the other Marvel games that have closed down - particularly Avengers Alliance. There's a Redux version being made, but the creator of that is clearly rebuilding it from scratch as an executable instead of an SWF, and there's clearly some missing code and files.

Bleeding Cool posted spoilers for Valkyrie #1, including the identity of who dies (the solicits revealed someone dies, but not who).
